ehmz is a Filipino YouTube singer with a boyish voice and a medium range who covers mainly VOCALOID and anime songs. His voice is said to be described as "genderless" and he is therefore considered a "ryouseirui". His true gender however, is not specified.

His most popular solo cover is "Period", which has over 33K views as of September 2014. His earliest cover still listed on his YouTube channel is "rain stops, good-bye", however he has been active since 2010 and like many other singers sometimes removes his older videos from public viewing.

Despite having a voice that sounds like it could be either male or female in many of his covers, he can pass for either gender on its own, for example, his feminine voice in his cover of "Senbonzakura".
